Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If curettage techniques are used to remove fat, then fat can be removed from the body, but the procedure becomes abrasive and involves high health risks
Solution Approach 1:
The patent replaces the mechanical curettage (scraping) system with a laser-based system that uses light energy to liquefy fat cells. The laser energy transforms the mechanical abrasion process into a thermal and optical process, where laser radiation heats and disrupts fat cell membranes, causing them to rupture and release contents that can be easily suctioned away, thereby eliminating the abrasive mechanical action while maintaining fat removal effectiveness
Solution Approach 2:
The patent utilizes phase transition of fat cells from solid/semi-solid state to liquid state through laser heating. The laser energy raises the temperature of fat cells to a point where their structural integrity breaks down and they transition to a liquid state, making them fluid and easily removable through suction, thus avoiding the need for mechanical scraping while ensuring safe and efficient fat removal
2Productivity
If suction-assisted removal with fluid infusion is used, then fat can be removed, but high volume fluid introduction causes body effects and toxicity concerns
Solution Approach 1:
The patent applies preliminary action by using laser energy to pre-liquefy fat cells before suction removal. The laser treatment breaks down fat cell structures and releases their contents in advance, transforming the fat into a liquid state that can be easily removed with minimal or no fluid infusion, thereby eliminating the need for large volumes of tumescent fluid and avoiding associated toxicity risks
Solution Approach 2:
The patent replaces the fluid infusion mechanism with a laser-based liquefaction system. Instead of introducing large volumes of fluid to facilitate fat removal, the system uses laser radiation to directly break down fat cell membranes and liquefy fat contents, substituting the hydraulic approach with an optical-thermal approach that eliminates fluid toxicity concerns while maintaining effective fat removal
3Productivity
If ultrasonic techniques are used to liquefy fat, then fat can be removed, but complications increase and raise concerns
Solution Approach 1:
The patent replaces the ultrasonic vibration system with a laser-based system. Instead of using high-frequency sound waves to mechanically disrupt fat cells, the system uses laser radiation to thermally heat and disrupt fat cell membranes, substituting acoustic energy with optical energy to achieve fat liquefaction with fewer complications and improved safety profile
Solution Approach 2:
The patent changes the physical parameter used for fat liquefaction from ultrasonic frequency vibration to laser wavelength and intensity. By adjusting laser parameters such as wavelength, power, and pulse duration, the system achieves effective fat cell disruption through thermal mechanisms rather than mechanical vibration, thereby maintaining liquefaction efficiency while reducing complication rates
4Reliability
If laser techniques are used to liquefy fat, then fat can be removed, but currently known procedures are underdeveloped and do not allow high efficiency fat removal
Solution Approach 1:
The patent merges laser lipolysis with suction-assisted lipectomy in a single integrated procedure. The laser component liquefies fat cells while the suction component simultaneously removes the liquefied fat, combining two separate processes into one coordinated system that achieves both effective fat breakdown and efficient fat removal, thereby improving overall productivity while maintaining procedure reliability
Solution Approach 2:
The patent implements continuous useful action by coordinating laser irradiation and suction removal to occur simultaneously and continuously throughout the procedure. As the laser continuously liquefies fat cells in real-time, the suction system continuously removes the liquefied fat, maintaining an uninterrupted process that maximizes fat removal efficiency without requiring separate stages for liquefaction and removal

AI summary
A minimally invasive fat cell removal system and method is provided using a numbing component, a laser component, and a NIL component. A cannula and fiber of the laser component are insertable into a body of a patient at a biopsy punch to liquefy a fat cell via a tumescent fluid and/or a laser. A NIL cannula of the NIL component is insertable into the body to remove the fat cell via suction and/or nutation. An anesthetic device of the numbing component may reduce sensation of the body where the cannula is insertable. The fat cell may be harvested and implanted at another location of the body.
